Brushless Pro's Please Help!

[vokus]

First of all Hi Every One,

I need any good advice I can get.

My Goal.

I would like to set up a stock E Maxx 3905 to take with me on trail hiking.
I would like to set it up for a walking to jogging speed.
I would like to have one set of batteries for the whole hike, I dont want to carry space batteries with me.

I need help understanding some concepts with the motor, voltage and capacity.


I would like to use the Mamba Monster ESC, because castle seems like they have a good warranty if anything break.

I would like to get TrueRC to make custom sized pack for me with the highest capacity possible to fit under the E Maxx body.

But before I order the packs I need to figure out what voltage I need to run this whole set up under.

Questions.

What would give me the longer run time.

High capacity and lower voltage or high capacity and high voltage.

What motor and pinion would you guys recommend I run in this setup?

I assume their is not going to be much load on the drive train because the car is going to be going slow, so what would be the best motor for this scenario?

Please feel free to give any additional information to me, Im new to this and anything helps.

Thank you for your time.
